Application November 23, 1954, Serial No. 470,763

2 Claims. (Cl. 296--) The present invention relates to side braces forthe walls of a grain wagon.

The principal object of the present invention is to provide a brace forthe side walls of a grain wagon and one that is adjustable to permit theside walls to be returned to a vertical position after they have beendeformed outwardly by the weight and bulk of grain carried by the wagon.

Another object of the present invention is to provide a brace for theside walls of a grain wagon box to permit the side walls to bereadjusted to a vertical position after they have been deformed by thebulk and weight of grain carried in the box and after the ends or sideedges of the platform have been deformed downwardly due to the bendingmovement of the side walls.

A further object of the present invention is to provide an adjustableside brace for the side walls of a grain wagon box of inexpensiveconstruction and one which is easy to attach to existing grain wagonboxes as an extra brace or to replace the braces attached to the sidewalls.

These and other objects of the present invention will be fully apparentfrom the following description when taken in conjunction with theannexed drawings, in which:

Figure 1 is a side view partly in cross section of the brace of thepresent invention :as attached to the side wall and platform of a grainwagon box;

Figure 2 is a front view in elevation of the present invention; and

Figure 3 is a vertical view in cross section on line 33 of Figure 2.

Referring in greater detail to the drawing in which like numeralsindicate like parts throughout the several views, the invention is seento consist of a brace 10 secured in an upstanding abutting position tothe side wall 11 of a grain wagon box or any other box on a vehiclewhich carries bulky and heavy loads.

Bolts or rivets 12 secure the brace 10 to the side wall 11 with thelower end 13 of the side wall resting upon a channel iron strip 14 onthe outer side edge of a platform 15.

The brace 10 is of L-shaped construction with one leg in abutting faceto face relation with the side wall 11 and with the other leg projectingperpendicularly to the side wall 11 and tapering from its lower end 16to its upper end 17.

A foot plate 18 is welded or otherwise secured to the lower end 16 ofthe brace 10 and is provided with a hole Patented Nov. 20, 1956 means ofa nut 21 which is in threaded engagement with the bolt below the strip14.

The foot plate 18 is also provided with another hole 22 to receive oneend of the bolt 23 which has its head 24 in abutting relation with thestrip 14 on the platform 15.

The hole 22 is preferably threaded, although not necessarily so, as thenut 25 forms a support for the foot plate 18.

As seen in dotted lines in Figure 1 at 26 the side wall may be swung atits upper end inwardly with respect to the platform to correct anyoutward bending due to the bulk or weight of the grain or other materialcarried in the wagon box. The vertically extending bolt 23 may be turnedor the nut 25 adjusted upwardly or downwardly to effect this swingingmovement.

The bolt 20 forms a fastening element securing the brace to the platformand adjustment of the nut 21 may be necessary to permit the swingingmovement of the upper end 26 of the side wall 11.

While a single embodiment of the present invention has been hereillustrated and described, it is believed that other embodiments may bemade and practiced within the scope of the appended claims withoutdeparting from the spirit of the invention.

What is claimed is:

l. The combination with a vehicle supported grain holding box includinga platform and a side wall carried by said platform adjacent a side edgethereof, of an upstanding brace arranged exteriorly of and abutting saidside wall and secured to said wall, the lower end of said brace beingspaced above said platform, a horizontally disposed foot plate securedto the lower end of said brace, a bolt supported in said foot plate andextending through said platform and adju-stably secured to the latter, asecond bolt spaced from said first bolt and extending through said footplate and having a head resting upon said platform, and a nut inthreaded engagement with said second bolt and having its upper facebearingagainst said foot plate.

2. The combination with a vehicle supported grain holding box includinga platform and :a side wall carried by said platform adjacent a sideedge thereof, of an upstanding brace of L-shape construction arrangedexteriorly of and having one of its legs abutting said side wall andsecured to said wall and having the other of its legs projectingperpendicularly from said wall, the lower end of said brace being spacedabove said platform, a horizontally disposed foot plate integrallysecured to the legs of said brace at the lower end thereof, a boltsupported in said foot plate and extending through said platform andadjustably secured to the latter, a threaded bolt spaced from said firstnamed bolt :and extending through said foot plate and having a headresting upon said platform, and a nut in threaded engagement with saidthreaded bolt and having its upper face bearing against said foot plate.
